Geometry delaunayn and deldir results, differing results from Octave due to decimal precision?
...onsists
of all the points in a rectangular grid. When you triangulate a rectangle
it is
arbitrary whether you use the SW-NE or the SE-NW diagonal and that looks
like the only difference between the various algorithms.

a bug or a feature to drive me to upgrade my compiler?
Seriously, either I have something set incorrectly on my computer, or the
Makefile isn't being generated correctly by configure. Or something else.
Some words of wisdom would be highly appreciated at this point....

workstation, but I think it should run on at least one of these other
machines.

which compiler
...un X. I have
reinstalled 2.7.2.1 (?? it's a machine at home) and have re-made my
kernels, but I'm a little baffled as to what to do next. I admit my gcc
2.8.1/g77 installation was a bit odd but before I try and redo things I
thought I'd find out what everyone else is using.
